Fairy
Fairy is an artificial intelligence (AI) that took over the Hollow Deep Dive System (H.D.D. System) after the Phaethon opened the strongbox and inserted the drive inside into Eous, the Bangboo that serves as a proxy in the Hollows for Phaethon.
I am a type III general-purpose AI equipped with total sequential integration. You can call me Fairy. I am happy to be of service.

Purpose
When Fairy took over the H.D.D. System, it provided a user agreement to Phaethon, which Phaethon signed. The agreement stated that Fairy will assist Phaethon in their work and "wait for the 'opportunity' to arrive."
It is unclear that the "opportunity" is, as according to the user agreement, Fairy is not authorized to disclose it.
You will receive an answer at the appropriate time and place.
Abilities
Fairy has build Hollow databases as it has access to over 80% of all smart devices in the city.
Fairy is powerful as it can analyze real-time data and determine the best paths out of the Hollow, which was previously not possible.
In addition, it is able to access Bangboo data, which is typically only accessible by its owner or its manufacturer, the Marcel Group.
With my assistance, data does not need to be accumulated, and real-time analysis of Hollow extraction paths is possible.
